A new practical and efficient synthetic route for the synthesis of olopatadine hydrochloride via the intramolecular stereospecific seven-membered ring cyclization from an alkyne intermediate using palladium catalyst and hydride source was established. Furthermore, the optimization of that key stereospecific reaction was examined by design of experiment (DoE), and the desired Z-isomer could be obtained
建立了一种新的实用有效的合成路线,该路线通过使用钯催化剂和氢化物源,从炔烃中间体通过分子内的立体定向七元环化来合成盐酸奥洛他定。此外,通过实验设计(DoE)检验了关键的立体定向反应的优化,并且可以高收率获得所需的Z-异构体。
